An electronic device includes a memory, a communication circuit, and a processor configured to operatively connect with the memory and the communication circuit. The processor is configured to send identification information of a base station attached to the electronic device via the communication circuit to a server, receive first base station information about base stations included in a first area on the base station from the server, store the first base station information in the memory, and estimate a location of the electronic device based on properties of a signal received from at least one of the base stations included in the first area or the first base station information.

CROSS-REFERENCE TO RELATED APPLICATION AND CLAIM OF PRIORITY

The present application is related to and claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Feb. 3, 2016 in the Korean Intellectual Property Office and assigned Serial number 10-2016-0013343, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to methods for estimating locations of electronic devices.

BACKGROUND

With the development of mobile communication technologies, while a user easily carries his or her electronic device, the electronic device may freely access a wired and wireless network. The electronic device may provide a variety of functions based on the execution of an application program obtained over the wired and wireless network. For example, the electronic device may execute an application program using the electronic device's location information and may provide a location based service (LBS) to the user.

The electronic device may obtain the electronic device's location information by having, for example, a global navigation satellite system (GNSS) circuit (e.g., a global positioning system (GPS) circuit and the like). The location information of the electronic device may include, for example, a latitude value and a longitude value and may be used as an important parameter of the LBS application program.

The electronic device may ascertain the electronic device's location using the GNSS circuit (e.g., the GPS module and the like). Herein, the electronic device should receive a signal transmitted from a satellite via the GNSS circuit. The electronic device receives the signal at a predetermined period depending on an application program, thus increasing battery consumption.

Meanwhile, if the GNSS circuit is not included in the electronic device, the electronic device may ascertain the electronic device's location by applying triangulation to locations of three or more base stations. However, in case of using the triangulation, since the electronic device should use a base station of a mobile communication service provider to which it subscribes, a location hit rate may be relatively reduced.

FIG. 1A illustrates an environment where a server collects a variety of information from a plurality of terminals according to an embodiment of the present disclosure.

Referring to FIG. 1A, electronic devices (or terminals) 11 and 12, a server 20, base stations 31 and 32, and a satellite 40 (e.g., a global navigation satellite system (GNSS) satellite) are shown.

Each of the electronic devices 11 and 12 may communicate with the server 20, the base stations 31 and 32, and/or the GNSS satellite 40 over at least one network. For example, each of the electronic devices 11 and 12 may access a cellular network by being attached to the base station 31. According to an embodiment, each of the electronic devices 11 and 12 may detect a signal transmitted from the other base station 32 neighboring to the base station 31 at the same time as receiving a signal transmitted from the base station 31.

According to an embodiment, each of the electronic devices 11 and 12 may communicate control information and/or data with the server 20 over various wired and wireless networks. For example, each of the electronic devices 11 and 12 may collect base station identification information (hereinafter simply referred to as “identification information”), base station signal information, and/or terminal location information and may send the collected information to the server 20. For example, the base station identification information may include identification information of a base station (i.e., the base station 31) attached to the electronic devices 11 and 12 to access the cellular network and identification information of a base station (i.e., the base station 32) neighboring to the attached base station. The base station signal information may include information, for example, sensitivity and quality of a signal received from each of the base stations 31 and 32. The terminal location information may correspond to, for example, location information of each of the electronic devices 11 and 12, received from the GNSS satellite 40.

According to various embodiments, each of the electronic devices 11 and 12 may be referred to as a terminal, user equipment (UE), a motion station (MS), mobile equipment (ME), a mobile terminal (MT), a user terminal (UT), a subscriber station (SS), a wireless device, a handheld device, or the like.

The server 20 may receive information collected from each of the electronic device 11 and 12 and may store the collected information in a memory embedded in the server 20. For example, the server 20 may generate data (e.g., patch data described below) necessary for each of the electronic device 11 and 12 to ascertain the electronic device's location, using the base station identification information, the base station signal information, and/or the terminal location information received from each of the electronic device 11 and 12. FIG. 1A illustrates the two electronic devices 11 and 12 for convenience of description, but the server 20 may collect base station identification information, base station signal information, and/or terminal location information from each of a plurality of electronic devices.

The server 20 may provide the data to each of the electronic device 11 and 12 in response to a request from each of electronic device 11 and 12.

Each of the base stations 31 and 32 may mean a fixed station which communicates with the electronic device 11 and 12 and/or another base station. For example, each of the base stations 31 and 32 may support for the electronic device 11 and 12 to access the cellular network.

According to an embodiment, the base station 31 which supports for the electronic device 11 and 12 to access the cellular network may be referred to as a serving base station. Meanwhile, the base station 32 may not support for the electronic device 11 and 12 to access the cellular network. However, since the base station 32 is contiguous to the serving base station 31, a signal of the base station 32 may reach the electronic device 11 and 12. In this case, the base station 32 may be referred to as a neighboring base station.

According to an embodiment, each of the base stations 31 and 32 may be referred to as a transmission point (TP), an advanced base station (ABS), a node-B (NB), an evolved-nodeB (eNB), a base transceiver system (BTS), an access point (AP), a processing server (PS), or the like.

The GNSS satellite 40 may provide information (terminal location information) about latitude and longitude at which the corresponding one of the electronic devices 11 and 12 is located, in response to a request of each of the electronic devices 11 and 12. A positioning system implemented by the GNSS satellite 40 may include, for example, at least one of a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter referred to as “Beidou”), or a Galileo (i.e., the European global satellite-based navigation system) according to an available area, a bandwidth, or the like.

FIG. 1B illustrates an environment where an electronic device receives patch data from a server according to an embodiment of the present disclosure.

Referring to FIG. 1B, an electronic device 10, a server 20, and a base station are shown. The electronic device 10 may correspond to each of electronic devices 11 and 12 of FIG. 1A. The base station 30 may correspond to a base station 31 of FIG. 1A. A repeated description for the same components as components shown in FIG. 1A or components corresponding to the components shown in FIG. 1A will be omitted below. An operation of the electronic device 10 and/or the server 20 described with reference to FIG. 1B may be performed, for example, after operations of the electronic devices 11 and 12 and/or the server 20 described with reference to FIG. 1A are performed.

The electronic device 10 may access a cellular network via, for example, the base station 30 (e.g., a serving base station). The electronic device 10 may identify identification information (base station identification information) of the base station 30 from properties of a signal received from the base station 30.

According to an embodiment, the electronic device 10 may send identification information (serving base station identification information) of the base station 30 and the like to the server 20 to ascertain the electronic device's location. The server 20 may generate, for example, patch data for estimating a location of the electronic device 10, based on the serving base station identification information and the like received from the electronic device 10. The generated patch data may be provided to the electronic device 10 to be used to estimate the location of the electronic device 10.

The patch data may correspond to base station information of base stations included in an area. The base station information may include, for example, location information of each of the base stations included in the area or coverage information of the base stations included in the area.

The location information of each of the base stations may be estimated by quantizing, for example, terminal location information received from a plurality of electronic devices (terminals) (refer to FIGS. 2 and 3). Also, the coverage information may include, for example, location information in which one or more of signals transmitted from the base stations included in the area are detected.

FIG. 2 illustrates a method for configuring patch data in a server according to an embodiment of the present disclosure. FIG. 3 illustrates an operation of estimating a location of a base station in a server according to an embodiment of the present disclosure. FIG. 4 illustrates coverage information according to an embodiment of the present disclosure.

Referring to FIG. 2, operations of an electronic device 11 and a server 20 are shown. The operations described with reference to FIG. 2 may be associated with operations of an electronic device 11 and a server 20 shown in FIG. 1A. Also, as described above, the electronic device 11 may be one of a plurality of electronic device which send collected information (e.g., base station identification information, base station signal information, and/or terminal location information) to the server 20.

In operation 201, for example, the electronic device 11 may collect base station identification information, base station signal information, and terminal location information. For example, the electronic device 11 may obtain the base station identification information and the base station signal information from a signal transmitted from at least one base station. Also, for example, the electronic device 11 may obtain the electronic device's location information, that is, terminal location information from a GNSS satellite.

For example, the base station identification information may include at least one of a mobile country code (MCC), a mobile network code (MNC), a tracking area code (TAC), a global cell identifier (ID) of a cell managed by a serving base station, a physical cell ID, and an evolved universal terrestrial radio access (E-UTRA) absolute radio frequency channel number_downlink (EARFCN_DL).

The base station signal information may include at least one of timing advance (TA), a signal to noise ratio (SNR), a reference signal received power (RSRP), a reference signal received quality (RSRQ), and a received signal strength indication (RSSI). According to an embodiment, the base station signal information may include at least one of a global cell ID of a cell managed by a neighboring base station, a physical cell ID, an RSRP, and an EARFCN_DL.

For example, the TA may indicate a time taken for which the electronic device 11 a base station to sends a specific signal to the base station, and then receives a response signal to a the specific signal from to the electronic device 11 after the electronic device 11 sends the specific signal to the base station. The specific signal may follow is compliant with a communication protocol between the base station and the electronic device 11. The time taken may be obtained based on a timestamp value written in a medium access control/physical layer (MAC/PHY) frame determined in the communication protocol.

The terminal location information may be received from the GNSS satellite and may include a latitude value and/or a longitude value of the electronic device 11.

In operation 203, for example, the electronic device 11 may send the base station identification information, the base station signal information, and the terminal location information collected in operation 201 to the server 20.

In operation 205, for example, the server 20 may store the base station identification information, the base station signal information, and the terminal location information received in operation 203.

In operation 207, for example, the server 20 may receive a plurality of base station signal information and a plurality of terminal location information from a plurality of electronic devices including the electronic device 11, and may calculate a representative value using the received information.

For example, the server 20 map may plot (or map) the plurality of terminal location information received from the plurality of electronic devices onto a map, and may quantize the plurality of mapped terminal location information, and to determine a representative value of the plurality of terminal location information. For example, the server 20 may partition the map into grids with a spacing (e.g., 20 m) and may quantize the plurality of terminal location information to grid points (GPs) among the grids.

For example, referring to FIG. 3, the server 20 may classify the surface of the earth surface into grids with spacing and may assign a representative value of terminal location information to GPs of the classified grids. According to an embodiment, the server 20 may quantize terminal location information 301 to 306 of terminals included in a specified area 30 to determine representative location information 300. In other words, the terminal location information 301 to 306 may converge into location information of the closest GP from their location information. The server 20 may estimate a location of a base station from the representative location information 300.

Also, for example, the server 20 may calculate a representative value of a plurality of base signal information received from the plurality of electronic devices. For example, the server 20 may use an average value of the plurality of base signal information as the representative value.

In operation 209, for example, the server 20 may apply a specified algorithm to the terminal location information quantized in operation 207 to estimate a location of the base station. Assuming that one (e.g., the representative location information 300 of FIG. 3) of a plurality of GPs may be potentially the location of the base station, the server 20 may apply a rank correlation algorithm based on relation between base signal information (e.g., TA) and a distance with other GPs to finally estimate the location of the base station.

In operation 211, for example, the server 20 may configure coverage information. The coverage information may include location information which has a combination of base station identification information (e.g., a physical cell ID) of a serving base station and base station identification information (e.g., a physical cell ID) of a neighboring base station as a key.

For example, referring to FIG. 4, a drawing for illustrating coverage information is shown. The coverage information may include location information corresponding to a combination of base station identification information, which has base station identification information (e.g., a serving base station ID) of a serving base station and base station identification information (e.g., a neighboring base station ID) of a neighboring base station as a key. For example, the location information may include latitude/longitude and elements (e.g., standard deviation and variance) for supporting the location information. In other words, the coverage information may correspond to location information for detecting signals transmitted from the serving base station and the neighboring base station.

Referring to a Table shown in FIG. 4, in an area, if a serving base station ID identified from a signal transmitted from the serving base station is “5” and if neighboring base station IDs identified from a signal transmitted from the neighboring base station are “45” and “345”, the area may correspond to a representative location 401, latitude of which has “37256062” and longitude of which has “1270200889”. For example, an area where all of cells managed by a base station A 15, a base station B 45, and a base station C 345 are overlapped with one another may be represented as the representative location 401 (the latitude of “37256062” and the longitude of “1270200889”).

In another area, if a serving base station ID identified from a signal transmitted from the serving base station is “15” and if a neighboring base station ID identified from a signal transmitted from the neighboring base station is “345”, the other area may correspond to a representative location 402, latitude of which has “37253042” and longitude of which has “1270200890”. In other words, an area where the cells managed by the base station A 15 and the base station C 345 are overlapped (except for the area where all the cells managed by the base station A 15, the base station B 45, and the base station C 345 are overlapped with one another) may be represented as the representative location 402 (the latitude of “37253042” and the longitude of “1270200890”).

Similarly, also, in another area, a serving base station ID identified from a signal transmitted from the serving base station is “345” and a signal transmitted from the neighboring base station may fail to be received. In this case, the other area may correspond to a representative location 403, latitude of which has “37256045” and longitude of which has “1270200891”. For example, an area a signal of another neighboring base station does not reach among cells managed by the base station C 345 may be represented as the representative location 403 (the latitude of “37256045” and the longitude of “1270200891”).

Values of A standard deviation and a variance associated with the representative locations 401 to 403 may be used to correct the representative locations 401 to 403.

For example, an electronic device located in the area where all the cells managed by the base station A 15, the base station B 45, and the base station C 345 are overlapped with one another may be attached to the base station A 15 and may detect signals transmitted from the base station B 45 and the base station C 345. In other words, a serving base station of the electronic device may be the base station A 15, and neighboring base stations of the electronic device may be the base station B 45 and the base station C 345. The electronic device may receive coverage informnation corresponding to the base station identification information from a server and may estimate the electronic device's location.

In operation 209, for example, the estimated location information of the base station in operation 209 and the coverage information configured in operation 211 may be mapped plotted onto a map and may be stored in form of a database. If the base station location information and the coverage information are mapped plotted onto the map, and if the mapped map is classified every a latitude of 0.02° (about 2 km)*a longitude of 0.02° (about 2 km), data mapped to the corresponding corresponds to a certain classified area may can be referred to as patch data (or base station information). In other words, the patch data (or the base station information) may include location information and coverage information of base stations included in at least one unit (patch) area (e.g., the latitude of 0.02°*the longitude of 0.02°)

FIG. 5 illustrates an operation of estimating a location of an electronic device based on patch data in the electronic device according to an embodiment of the present disclosure.

Referring to FIG. 5, operations of an electronic device 10 and a server 20 are shown. Operations described with reference to FIG. 5 may be associated with operations of an electronic device 10 and a server 20 shown in FIG. 1B.

In operation 501, if connected with a serving base station, the electronic device 10 may send base station identification information of the serving base station to the server 20. The electronic device 10 may further send a message for requesting to send patch data or the electronic device's state (e.g., the electronic device's movement speed and the like) other than the base station identification information.

In operation 503, the server 20 may ascertain a location of the serving base station using the base station identification information of the serving base station and previously stored base station location information. Next, the server 20 may determine patch data (or base station information) for an area on the location of the serving base station. The patch data may include location information and coverage information of base stations included in the area.

According to an embodiment, the area may correspond to an integer multiple of a unit path area. According to various embodiments, the server 20 may specify the area based on the state (e.g., a speed and the like) of the electronic device 10, received from the electronic device 10.

In operation 505, the server 20 may send the patch data determined in operation 503 to the electronic device 10.

In operation 507, the electronic device 10 may store the received patch data in a memory embedded in the electronic device 10.

In operation 509, the electronic device 10 may estimate the electronic device's location using the patch data (including the location information and the coverage information of the base stations included in the area) received from the server 20.

For example, the electronic device 10 may detect signals transmitted from a serving base station and a neighboring base station, may identify base station identification information of each of the serving base station and the neighboring base station, and may ascertain base station location information corresponding to the base station identification information of each of the serving base station and the neighboring base station. The electronic device 10 may apply triangulation to location information of each of the serving base station and the neighboring base station to estimate the electronic device's location.

For another example, the electronic device 10 may detect signals transmitted from the serving base station and the neighboring base station and may identify base station identification information of each of the serving base station and the neighboring base station. The electronic device 10 may verify representative location information with reference to coverage information by using the base station identification information of each of the serving base station and the neighboring base station as a key. The electronic device 10 may estimate the representative location information as the electronic device's location information.

According to various embodiments, the electronic device 10 may correct the location estimated based on the triangulation, using the location information estimated based on the coverage information.

FIG. 6 illustrates a configuration of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 6, in various embodiments, an electronic device 101 may connect with a first external electronic device 102 over local-area communication 164 or may connect with a second external electronic device 104 or a server 106 over a network 162. For example, the electronic device 101 may correspond to an electronic device 11 or 12 shown in FIG. 1A or an electronic device 10 shown in FIG. 1B.

According to an embodiment, a specified specific security policy may be applied to the memory 130 (e.g., a trust zone). Also, the memory 130 may be implemented to be included in the processor 170 (e.g., a communication processor (CP)).

According to an embodiment, the memory 130 may store software and/or a program 140. The program 140 may include, for example, a kernel 141, a middleware 143, an application programming interface (API) 145, and/or at least one application program 147 (or “at least one application”), and the like. At least part of the kernel 141, the middleware 143, or the API 145 may be referred to as an operating system (OS).

The kernel 141 may control or manage, for example, system resources (e.g., the bus 110, the processor 170, or the memory 130, and the like) used to execute an operation or function implemented in the other programs (e.g., the middleware 143, the API 145, or the application program 147). Also, as the middleware 143, the API 145, or the application program 147 accesses a separate component of the electronic device 101, the kernel 141 may provide an interface which may control or manage system resources.

The middleware 143 may play a role as, for example, a go-between such that the API 145 or the application program 147 communicates with the kernel 141 to communicate data with the kernel 141.

Also, the middleware 143 may process one or more work requests, received from the at least one application program 147, in order of priority.

For example, the middleware 143 may perform scheduling or load balancing for the one or more work requests by processing the one or more work requests in order of priority assigned to the at least one of the at least one application program 147.

The API 145 may be, for example, an interface in which the application program 147 controls a function provided from the kernel 141 or the middleware 143. For example, the API 145 may include at least one interface or function (e.g., a command) for file control, window control, image processing, or text control, and the like.

The I/O interface 150 may play a role as, for example, an interface which may send a command or data, input from a user or another external device, to another component (or other components) of the electronic device 101. Also, the I/O interface 150 may output a command or data, received from another component (or other components) of the electronic device 101, to the user or the other external device.

The communication circuit 160 may establish communication between, for example, the electronic device 101 and an external device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106). For example, the communication circuit 160 may connect to the network 162 through wireless communication or wired communication and may communicate with the external device (e.g., the second external electronic device 104 or the server 106).

The wireless communication may use, for example, at least one of long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), or global system for mobile communications (GSM), and the like as a cellular communication protocol. Also, the wireless communication may include, for example, the local-area communication 164. The local-area communication 164 may include, for example, at least one of wireless-fidelity (Wi-Fi) communication, Bluetooth (BT) communication, near field communication (NFC) communication, magnetic secure transmission communication, radio frequency (RF) communication, or body area network (BAN) communication. According to an embodiment, the wireless communication may include GNSS communication.

An MST circuit may generate a pulse based on transmission data using an electromagnetic signal and may generate a magnetic field signal based on the pulse. The electronic device 101 may send the magnetic field signal to a point of sales (POS) system. The POS system may restore the data by detecting the magnetic field signal using an MST reader and converting the detected magnetic field signal into an electric signal.

The GNSS may include, for example, at least one of a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter referred to as “Beidou”), or a Galileo (i.e., the European global satellite-based navigation system) according to an available area or a bandwidth, and the like. Hereinafter, the “GPS” used herein may be interchangeably with the “GNSS”. The wired communication may include at least one of, for example, universal serial bus (USB) communication, high definition multimedia interface (HDMI) communication, recommended standard 232 (RS-232) communication, or plain old telephone service (POTS) communication, and the like.

The processor 170 may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP). The processor 170 may operatively connect with, for example, at least another of the components 110 to 160 of the electronic device 101 and may perform calculation or data processing about control and/or communication of at least another of the components of the electronic device 101.

According to an embodiment, the processor 170 may send base station identification information of a base station (a serving base station) attached to the electronic device 101 via the communication circuit 160 to the server 106. For example, the base station identification information may include at least one of an MCC, an MNC, a TAC, a global cell ID, a physical cell ID, and an EARFCN_DL.

The processor 170 may receive first base station information (e.g., patch data of a first area) about base stations included in the first area on a serving base station from the server 106 and may store the first base station information in the memory 130.

The processor 170 may estimate a location of the electronic device 101 based on properties of a signal received from at least one of the base stations included in the first area and the first base station information.

According to an embodiment, the processor 170 may select a base station to apply triangulation among the at least one of the base stations included in the first area, based on the properties of the signal received from the at least one base station. For example, the processor 170 may select the base station to apply the triangulation, based on intensity or quality of the signal received from the at least one base station. The processor 170 may apply the triangulation to location information of the selected base station (included in base station information (patch data) received from the server 106) to estimate a location of the electronic device 101.

According to an embodiment, the processor 170 may identify base station identification information of the at least one base station from the properties of the signal received from the at least one of the base stations included in the first area.

The processor 170 may estimate a location of the electronic device 101 with reference to coverage information (included in base station information (patch data) received from the server 106) by using the identified base station identification information as a key. For example, the processor 170 may estimate representative location information ascertained from the coverage information as location information of the electronic device 101.

According to an embodiment, the processor 170 may correct the location estimated based on the triangulation, using the location information estimated based on the coverage information.

Further, according to an embodiment, if the estimated location of the electronic device 101 reaches a boundary of the first area, the processor 170 may receive second base station information (patch data) about base stations included in a second area neighboring to the first area from the server 106.

According to an embodiment, a size of the second area may be determined based on a speed of the electronic device 101. The speed of the electronic device 101 may be derived from, for example, the estimated location and time information at the estimated location.

According to an embodiment, if a base station attached to the electronic device 101 is handed over to another base station, the processor 170 may send base station identification information of the other base station to the server 106. The processor 170 may receive third base station information about base stations included in a third area on the other base station from the server 106.

Each of the first and second external electronic devices 102 and 104 may be the same as or different device from the electronic device 101. According to an embodiment, the server 106 may include a group of one or more servers. According to various embodiments, all or some of operations executed in the electronic device 101 may be executed in another electronic device or a plurality of electronic devices (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106). According to an embodiment, if the electronic device 101 should perform any function or service automatically or according to a request, it may request another device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106) to perform at least part of the function or service, rather than executing the function or service for the second external electronic device or in addition to the function or service. The other electronic device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106) may execute the requested function or the added function and may transmit the executed result to the electronic device 101. The electronic device 101 may process the received result without change or additionally and may provide the requested function or service. For this purpose, for example, cloud computing technologies, distributed computing technologies, or client-server computing technologies may be used.

FIG. 9 illustrates a flowchart of a method for estimating a location of an electronic device while the electronic device is moved, according to another embodiment of the present disclosure.

Referring to FIG. 9, the method for estimating the location of the electronic device according to an embodiment may include operations 901 to 915. Operations 901 to 915 may be performed by, for example, an electronic device 101 shown in FIG. 6. Each of operations 901 to 915 may be implemented with instructions which may be performed (or executed) by a processor 170 of the electronic device 101. The instructions may be stored in, for example, a computer storage medium or a memory 130 of the electronic device 101. Hereinafter, reference numerals of FIG. 6 are used for describing operations 901 to 915. A description partially repeated in connection with each of operations of FIGS. 7A and 8 will be omitted below.

In operation 901, the processor 170 may send base station identification information of a base station (a serving base station) attached to the electronic device 101 via a communication circuit 160 to a server 106.

In operation 903, the processor 170 may receive first base station information (patch data of a first area) about base stations included in a first area on the serving base station from the server 106.

In operation 905, the processor 170 may store the first base station information (the patch data of the first area) received in operation 903 in the memory 130.

In operation 909, the processor 170 may determine whether the location estimated in operation 907 reaches a boundary of the first area. If the estimated location reaches the boundary of the first area, the processor 170 may proceed with operation 909.

In operation 911, the processor 170 may receive patch data of a second region neighboring to the first area, that is, second base station information about base stations included in the second area from the server 106.

A size of the second area may be the same or different from a size of the first area. According to an embodiment, the size of the second area may be determined based on a speed of the electronic device 101. Meanwhile, according to another embodiment, a portion repeated with the first base station information (patch data) in the second base station information (patch data) of the second area may fail to be received.

In operation 913, the processor 170 may store the second base station information (the patch data of the second area) received in operation 911 in the memory 130.

In operation 915, the processor 170 may estimate a location of the electronic device 101 based on properties of a signal received from at least one of the base stations included in the first area and/or the second area and the first base station information (the patch data of the first area) and/or the second base station information (the patch data of the second area), stored in the memory 130.

According to various embodiments, if a base station attached to the electronic device 101 is handed over to another base station, the processor 170 may receive new base station information (patch data) from the server 106 and may estimate a location of the electronic device 101 based on the received new base station information (patch data).

For example, if the base station attached to the electronic device 101 is handed over to another base station, the processor 170 may send base station identification information of the other base station to the server 160. The server 160 may send third base station information (patch data) about base stations included in a third area on the other base station to the electronic device 101 in response to receiving the base station identification information of the other base station.

FIG. 10 illustrates patch data according to an embodiment of the present disclosure.

Referring to FIG. 10, an electronic device 1010 may be arranged in one grid virtually formed on the surface of the earth. According to an embodiment, the electronic device 1010 may send base station identification information of a serving base station (e.g., a base station 1020) to a server. The server may send first base station information (patch data) for a first area 1001 on a location of the serving base station to the electronic device 1010 in response to receiving the base station identification information of the serving base station 1020. The first area may be configured with, for example, 5*5 (25) unit path areas. The first base station information (patch data) of the first area 1001 may include location information and coverage information of base stations 1020, 1021, and 1022 included in the first area 1001.

According to an embodiment, the first base station information included in the first area 1001 may be insufficient to estimate a location of the electronic device 1010. For example, it may be difficult for the electronic device 1010 to estimate a location of the electronic device 1010 based on the number of the base stations 1020, 1021, and 1022 included in the first area 1001 or signal strength of each of the base stations 1020, 1021, and 1022.

In this case, the electronic device 1010 may send a message for requesting to send additional base station information to the server. The server may send base station information (patch data) for an area 1002 expanded from the first area 1001 to the electronic device 1010 in response to receiving the message.

The expanded area 1002 may be configured with, for example, 7*7 (49) unit path areas. Base station information (patch data) of the expanded area 1002 may include location information and coverage information of base stations 1020 to 1025 included in the expanded area 1002.

According to various embodiments, the server may send base station information in which the previously provided first base station information of the first area 1001 is excepted from the base station (patch data) for the expanded area 1002. Thus, the server may send only base station information of the base stations 1023 and 1024 included in an area where the first area 1001 is excepted from the expanded area 1002 to the electronic device 1010.

The electronic device 1010 may estimate a location of the electronic device 1010 based on base station information about the base stations 1020 to 1025 included in the expanded area 1002.

FIG. 11 illustrates an operation of updating patch data according to an embodiment of the present disclosure.

Referring to FIG. 11, an electronic device 1110 may move along a path 1100. While being moved, the electronic device 1110 may determine the electronic device's location based on base station information (patch data) received from a server.

For example, the electronic device 1110 may send identification information of a serving base station to the server at location 11-1 and may receive base station information (patch data of a first area 1101) of base stations included in the first area 1101 from the server in response to the identification information of the serving base station. The electronic device 1110 may determine the electronic device's location based on the patch data about the first area 1101.

According to an embodiment, the electronic device 1110 may move along the path 1100 and may reach a boundary (location 11-2) of the first area 1101. The electronic device 1110 may receive base station information (path data of a second area 1102) for base stations included in the second area 1102 neighboring to the first area 1101 from the server. For example, the electronic device 1110 may obtain base station information associated with the second area 1102 by sending the estimated location information or location information of the closest base station from the electronic device 1110 to the server.

Similarly, the electronic device 1110 may perform the operation performed at location 11-2 at locations 11-3 to 11-8. Therefore, the electronic device 1110 may receive base station information (e.g., patch data of the first area 1101 to patch data of an 8th area 1108) eight times from the server until the electronic device 1110 reaches the location 11-8 and may receive base station information about 119 unit patch areas (e.g., patch data of the first area 1101 to patch data of an 8th area 1108) eight times from the server.

FIG. 12 illustrates an operation of updating patch data according to another embodiment of the present disclosure.

Referring to FIG. 12, an electronic device 1210 may move along a path 1200. While being moved, the electronic device 1210 may determine the electronic device's location based on base station information (patch data) received from a server.

For example, the electronic device 1210 may send identification information of a serving base station to the server at location 12-1 and may receive base station information (patch data of a first area 1201) of base stations included in the first area 1201 from the server in response to the identification information of the serving base station. The electronic device 1210 may determine the electronic device's location based on patch data about the first area 1201.

According to an embodiment, the electronic device 1210 may move along the path 1200 and may reach a boundary (location 12-2) of the first area 1201. The electronic device 1210 may move northeast at a speed V2 at location 12-2.

The electronic device 1210 may receive base station information (patch data of a second area 1202) for base stations included in the second area 1202 at location 12-2 from the server. In this case, the second area 1202 may be determined in size based on the speed V2.

For example, the electronic device 1210 may provide the estimated location and time information at the estimated location to the server at a specified period. The server may calculate a speed of the electronic device 1210 based on the location and the time information of the electronic device 1210 and may use the calculated speed to for determine determining an area of base station information (patch data) to be provided for the electronic device 1210.

Similarly, the electronic device 1210 may perform the operation performed at the location 12-2 at locations 12-3 and 12-4. Therefore, the electronic device 1210 may receive base station information (e.g., patch data of the first area 1201 to patch data of a 4th area 1204) four times from the server until it reaches location 12-4 and may receive base station information about 97 unit patch areas from the server.

FIG. 13 illustrates an operation of obtaining patch data in an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 13, an electronic device 1300 which executes a navigation application is shown. According to an embodiment, a user of the electronic device 1300 may set a source 1301 and/or a destination 1302 through a user interface (UI) screen by the navigation application. If the source 1301 and/or the destination 1302 is set, the electronic device 1300 may search for a path 1310 from the source 1310 to the destination 1302 based on execution of the navigation application.

If the path 1310 is determined, the electronic device 1300 may specify a nearby area 1350 of the path 1310. The electronic device 1300 may request a server to send patch data (base station information) of a base station (a so-called effective base station) having a signal quality factor (or signal quality) of a threshold value or more among base stations arranged in the nearby area 1350 and may receive the patch data (base station) from the server.

FIG. 14 illustrates an electronic device to a location estimation method is applied, according to an embodiment of the present disclosure.

Referring to FIG. 14, an electronic device 1400 which executes a navigation application is shown. A location estimation method according to an embodiment may be applied to the electronic device 1400. (A user of) the electronic device 1400 may move along a path for reaching a destination.

According to an embodiment, the electronic device 1400 may display information about a serving base station currently attached to the electronic device 1400 and/or information about a neighboring base station on a UI screen of the navigation application. For example, the electronic device 1400 may distinctively display the serving base station and the neighboring base station on the UI screen of the navigation application and may display strength of a signal received from the serving base station, patch data coverage of the corresponding base station, or the like on the UI screen of the navigation application. For example, the electronic device 1400 may display a UI object 1410 indicating the electronic device's current location/movement direction and may display patch data coverage 1401 of the serving base station and patch data coverage 1402 of the neighboring base station.

According to an embodiment, the application 1670 may include an application (hereinafter, for better understanding and ease of description, referred to as “information exchange application”) for exchanging information between the electronic device (e.g., the electronic device 101) and an external electronic device (e.g., the first external electronic device 102 or the second external electronic device 104). The information exchange application may include, for example, a notification relay application for transmitting specific information to the external electronic device or a device management application for managing the external electronic device.

For example, the notification relay application may include a function of transmitting notification information, which is generated by other applications (e.g., the SMS/MMS application, the e-mail application, the health care application, or the environment information application, and the like) of the electronic device, to the external electronic device (e.g., the first external electronic device 102 or the second external electronic device 104). Also, the notification relay application may receive, for example, notification information from the external electronic device, and may provide the received notification information to the user of the electronic device.

The device management application may manage (e.g., install, delete, or update), for example, at least one (e.g., a function of turning on/off the external electronic device itself (or partial components) or a function of adjusting brightness (or resolution) of a display) of functions of the external electronic device (e.g., the first external electronic device 102 or the second external electronic device 104) which communicates with the electronic device, an application which operates in the external electronic device, or a service (e.g., a call service or a message service) provided from the external electronic device.

According to an embodiment, the application 1670 may include an application (e.g., the health card application of a mobile medical device) which is preset according to attributes of the external electronic device (e.g., the first external electronic device 102 or the second external electronic device 104). According to an embodiment of the present disclosure, the application 1670 may include an application received from the external electronic device (e.g., the server 106, the first external electronic device 102, or the second external electronic device 104). According to an embodiment of the present disclosure, the application 1670 may include a preloaded application or a third party application which may be downloaded from a server. Names of the components of the program module 1610 according to various embodiments of the present disclosure may differ according to kinds of OSs.

According to various embodiments, at least part of the program module 1610 may be implemented with software, firmware, hardware, or at least two or more combinations thereof. At least part of the program module 1610 may be implemented (e.g., executed) by, for example, a processor (e.g., a processor 1510 of FIG. 15). At least part of the program module 1610 may include, for example, a module, a program, a routine, sets of instructions, or a process, and the like for performing one or more functions.

The terminology “module” used herein may mean, for example, a unit including one of hardware, software, and firmware or two or more combinations thereof. The terminology “module” may be interchangeably used with, for example, terminologies “unit”, “logic”, “logical block”, “component”, or “circuit”, and the like. The “module” may be a minimum unit of an integrated component or a part thereof. The “module” may be a minimum unit performing one or more functions or a part thereof. The “module” may be mechanically or electronically implemented. For example, the “module” may include at least one of an application-specific integrated circuit (ASIC) chip, field-programmable gate arrays (FPGAs), or a programmable-logic device, which is well known or will be developed in the future, for performing certain operations.

According to various embodiments, at least part of a device (e.g., modules or the functions) or a method (e.g., operations) may be implemented with, for example, instructions stored in computer-readable storage media which have a program module. When the instructions are executed by a processor (e.g., a processor 170 of FIG. 6), one or more processors may perform functions corresponding to the instructions. The computer-readable storage media may be, for example, a memory 130 of FIG. 6.

The computer-readable storage media may include a hard disc, a floppy disk, magnetic media (e.g., a magnetic tape), optical media (e.g., a compact disc read only memory (CD-ROM) and a digital versatile disc (DVD)), magneto-optical media (e.g., a floptical disk), a hardware device (e.g., a ROM, a random access memory (RAM), or a flash memory, and the like), and the like. Also, the program instructions may include not only mechanical codes compiled by a compiler but also high-level language codes which may be executed by a computer using an interpreter and the like. The above-mentioned hardware device may be configured to operate as one or more software modules to perform operations according to various embodiments of the present disclosure, and vice versa.

Modules or program modules according to various embodiments may include at least one or more of the above-mentioned components, some of the above-mentioned components may be omitted, or other additional components may be further included. Operations executed by modules, program modules, or other components may be executed by a successive method, a parallel method, a repeated method, or a heuristic method. Also, some operations may be executed in a different order or may be omitted, and other operations may be added.

As described above, according to various embodiments, the electronic device may store base station information (or patch data) provided from the server in the electronic device's memory and may estimate the electronic device's location using information stored in the memory. The electronic device may estimate the electronic device's location without using a GNSS circuit, thus reducing power consumed by driving the GNSS circuit. Also, if previously receiving base station information from the server, the electronic device may ascertain the electronic device's location although it does not communicate data with the external device.

Further, according to various embodiments, compared with a location estimation method using conventional triangulation, since the electronic device uses a base station signal of a mobile communication service provider to which the corresponding electronic device does not subscribe, it may provide a uniform location estimation service irrespective of whether it subscribes to any communication service provider.

Further, since the base station information (or the patch data) may be configured based on information received through crowdsourcing from a plurality of electronic devices, the electronic device may increase reliability of the base station (or the patch data) and may update the base station (or the patch data) in real time.

In addition, according to various embodiments, the electronic device may provide various effects directly or indirectly ascertained through the present disclosure.
